I want to create a two-node cluster, which uses the internal storage as shared storage. I don’t have any external storage. I know about Starwind and other third-party products but I can’t use that. Is it possible to achieve this only with Microsoft products. I read a lot about this problem but I couldn’t find a simple, yes it is possible or no it isn’t. Did someone do that before or tried it and failed? Would it be better to simply use Hyper-V Replica? I use Windows Server 2012 R2 on two Dell Poweredge R720 Servers. Thanks for help


You need to upgrade to Windows Server 2016 and pay super-expensive Datacenter edition tax for your both hosts just to use Microsoft built-in SDS tech similar to what "Starwind and other third-party tools" are doing: it's called Storage Spaces Direct (S2D).


It's pretty new (released October 2016) and lacks GUI (except you go for a SCVMM which is a complete overkill for a dual host cluster setup) and isn't getting anywhere close to say StarWind, VMware VSAN or HPE VSA in terms of maturity.

Also make sure you realize S2D within two and three node setups (except 3-way replication with later) isn't immune to a second failure so having faulty disk during one node reboot brings whole cluster down once and forever. Performance isn't great either: you won't get anywhere close to what your physical NVMe & SSD drives can do.
